To all whom it may concern:

Be it known that I, GUsTAv Kommun, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented een tain new and useful Improvements in Machines for Manufacturing Punches, Dies, and other Articles, of which the following is a specification.

My invention relates to a novel machine for the manufacture of various articles of manufacture, suoli punches, dies, and analogous articles, and it consists of the construction, combination, and arrangement of devices and appliances hereinafter described and claimed and illustrated in the accompanying drawings, in which- Figure 1 is a view in front elevation showing parts in section. Fig. 2 is a view in side elevation. Fig. 3 is a detail view in elevation showing the eccentric in place. Fig. 4 is a detail view in section on the line 4 4 Fig. 2, showing the eccentric in place. Fig. 5 is a plan view, the table removed. Fig. G is a view of the lathe attachment, parts being in sect-ion and parts in side elevation. Fig. 7 illustrates a modification in which a special arm is employed serving as a holder and guide for tools in use, shovw ing parts in section and parts in elevation. Fig. 8 is a detail view of certain parts in vertical section, showing the attachments of the connecting rod. Fig. 9 is a detail view of certain clamping mechanism in elevation. Fig. 10 is a view in section on the line 10-10 Fig. 9. Fig. 11 is a detail view of the segmental arms. Fig. 12 is a detail View showing the counter weights upon the pulley.

More particularly my invention has for its object, a machine of this class for filing, lapping, grinding, milling, buiiing, sawing, turning, and the like, which operations are now for the most part performed by hand, resulting in lack of accuracy and uniformity of production. My invention also greatly economizes the cost of such operations.

My invention is designed to provide rigid and unvarying fastenings for certain tools used in the work, and to provide a method of imparting uniform motion to such tools, together with means for holding the articles of manufacture up to the tools.

With these objects in view my invention consist-s of a suitable base upon which is mounted a machine with all its appurtenances including, preferably, a motor (not shown) for driving the machine the machine as a whole thus constituting a portable self contained apparatus that may be used anywhere, as by connecting the motor with any ordinary electric light circuit. The location of the motor, however, is not an essential feature, and the machine may be actuated by any suitable source of power.

I carry out my invention as follows: Any suitable base is indicated by the numeral 1 upon which the machine is located. Upon said base is mounted a suitable frame or support 2 provided, preferably, with a conical bearing 3 to receive a corresponding hollow spindle 4 provided with a hub 5, with which is engaged a connecting rod 6. To this end the said hub is provided with an eccentric A to which the connecting rod is attached by means of a screw a tapped into said eccentric toward its periphery. Upon said support are mounted vertically reciprocatory plungers 7 and 8, and an adjustable table 9, said table being provided with a depending arm 1() engaged with said support by a bolt 11. The plunger 8 has a threaded engagement in a reciprocatory post B in the support 2, as shown. The plunger 7 passes through said support, suitable clampingdevice (l holding the lower ends of the post B .and the plunger 7 parallel and in union during motion.

A tubular carrier post is shown at 12, preferably made of aluminum to secure lightness of construction, said carrier post being provided at the lower end thereof with a horizontal arm 18 secured upon the plunger 8 mounted upon said support. Upon said carrier post is supported an angu lar arm 14, the vertical portion 15 of which is preferably made hollow for a portion of its length, said angle arm being also provided with a horizontal portion 16. The angle arm 14 is adjustably mounted upon the carrier post 12, the adjustment of the vertical portion 15 being limited by a collar D and set screw d, the vertical arm being clamped in adjusted position by a set screw 17, the arm 12 being split in order to be clamped upon the vertical portion 15.

The plunger 8 is shown provided witha head 18 constructed preferably, with an opening 19 for the engagement therewith of a pin wrench, in attaching or detaching the plun er 8 from the post B. The plunger 8 is c amped to the arm 13 of the carrier post by means of a set screw 21 engaging los a split portion of the arm 13. The carrier post 12 is also provided with a horizontal arm 22 with which is engaged a tool carrier 23, hereinafter described, clamped into the arm 22 by means of a set screw 24 engaging a split portion of the arm 22.

The spindle 4 is supported at its outer end by a bearing 25 attached to the base as by means of a screw 26. rl`he connecting rod 6 connects the spindle 4 with the tool carrier 23. Said spindle 4 is made adjustable in its bearings by means of lock nuts 29 and 30. A stepped pulley 27 is keyed upon the spindle 4 by means of a key 31. The web of the pulley has two counter weights 33 attached thereto by means of screws 34, the web being provided with corresponding holes 35 to permit change of Y position of the counter-weights when the reciprocating parts are not in use.

The table 9 has a limited adjustment, to effect which, is shown a tapering pin 36 fitted into a corresponding hole 37 upon the center line of the bolt 11, so that when the said pin is engaged in the corresponding hole the table will have a perfectly level position, but when the pin is located in a corresponding hole 37 in another predetermined position, said table may take a correspondingly inclined position depending upon the location of other corresponding holes 37 in the frame or support 2, the holes 37 passing also through the arm 10 of the table. then the pin 36 is removed the table may be raised to a point where the bolt 11 will pass through the hole 38 instead of the hole 39.

In Figs. 1 and 2 is shown means of attaching various tools, such as tiles, saws, and other analogoustools, a file, for example, being shown at 20. The tools attached to the machine may be suspended from the horizontal portion 16 of the arm 14 and work from above, or the tools may project upward from the tool carrier 23, and work from below, passing through an opening 40 in the table, or again the tools may be connected rigidly to both the arm 16 and carrier 23 as shown in Fig. 7 and adjusted to a perpendicular position. The upper connection of the tools with the arm 16 may be made by means of a screw E passing through the arm 16 and bearing against a lug or jaw 42. Opposite the jaw 42 is an additional lug or vjaw 43 adjusted by a screw 41. The tool to be used is then clamped between the jaws 42 and 43, the engaged faces of the aws being cut away intermediate the ends of the jaws to form a projecting portion at each end of each jaw to engage the tool, and the back of each jaw is curved throughout the length of the jaw so that when the jaw 43 is adjusted by the set screw 41 which passes through a laterally projecting lug upon its upper end, said jaws will by reason of such curvature, turn within their seat in the arm to tilt the tool to the desired angle. l`he lower connection of the tools with the carrier 23 may be made by means of a jaw t4 with which is engaged a pin 45 working in an oblong slot 46 in a clamp 47 actuated by a screw 48. Likewise a jaw 4) actuated by a screw 50 holds the tool from the opposite side. These jaws 44 and 45 are curved similar to the jaws 42 and 43 and are adapted to be tilted or turned within their holder by the set screw 50 in a manner similar to that in which said jaws 42 and 43 are adjusted.

The eccentric connection of the rod G above described affords a method of adjusting various structures of the machine, the great advantage of which is that the clamping of the eccentric is positive and not depending upon friction between the, adjacent parts. Upon the circumference of the eccentric are drilled, preferably equidistant, hole:-l 53 corresponding to the points of the screws 54 securing the eccentric in the hub 5 by removing which the eccentric may be turned in either direction and again set rigidly in desired position.

In Fig. 7 is presented means for guiding very slender tiles, or other light tools which may be required, and for holding them in vertical position entirely free from lateral vibration. In the modification illust rated iu Fig. 7 the arm 63 is shown jointcdly counected with the vertical portion 76 of the arm 77, as indicated at 55, so that said arm 63 may be swung back and forth, and upon said arm 63 is movably engaged a sleeve l carrying the forked arm 51 carrying a segmental arln 52 said segmental arm 5l constructed with a slot Z) in its outer end to receive the tool therebetween. lVhen the two segmental arms are in contact with the tool the sleeve is clamped tight by means of a` screw 56 said sleeve being split for this purpose. The two segmental arms are then clamped together by screws 57 and the work may then be slipped along the tool in the direction of the arrow, and the tool will not vibrate or change its perpendicular position. lWithin the vertical portion 76 of the arm 77 is a plunger 5S against which bears the arm 63 to hold the arm in elevated position. The plunger 58 bears upon a spring 5t) which may be adjusted for tension by means of a stud 60 threaded into the vertical hollow arm 76 within the carrier post l2.

For certain processes the reciprocating parts heretofore described are essential. Where other kinds of work are to he done, means are employed, to produce uniform rotary motion.

there a milling, grinding, or bntling implement 61 is to be employed, the shank of the implement is inserted into the tapering hole 62 in the spindle 4 and driven up. An angle plate or bracket 64 secured to the base by a screw 7 5 serving the purpose of a table for the work, is then attached to the base 1. The implement 61 and bracket 64 may, however, be left on the machine when the reciprocatory parts are in use. When a lathe attachment is to be employed, shown in Fig. 6, the spindle or stud 73 of the lathe attachment is then inserted into the tapering hole 62 of the spindle f1 after the milling device has been removed. The lathe attachment comprises a chuck 65 of any desired construction attached to the tapering stud 73. A bar 66 serves as a holder lfor a block 67 which carries the tool rest 68 furnished with pins G9 for confining the desired cutting tool in place. A piece of work is indicated at 70.

The support 2 is provided with a horizontal arm 71 through which the plunger 7 passes. The tool carrier 23 is provided `with a stem 72 having a threaded engagement in the said plunger 7 It is evident that certain prts of the machine are thus interchange a le.

By the employment of the oscillatory arm 63 shown in Fig. 7 of the drawings, a workman is enabled to remove the arm carrying the tool and take out the work for examination, and to put it back, the tool being already in position for work when the oscillatory arm is restored to working position.

The counterbalance weights upon the pulley are employed in order to prevent vibration when the reciprocatory parts are used. When the rotary tools are employed the counterbalance weights will be arranged radially, as shown in dotted lines in Fig. 12.

Fig. 3 shows the hub provided with index orV scale marks to facilitate the adjustment of the eccentric A into desired position. The connecting rod is engaged with the carrier 23 by means of a pin e held in position by a screw 7 4f. 'Ihe end of the carrier 23 engaged in the arm 22 is made hollow as shown in Fig. 1.

`When a considerable amount of turning. buiiing, or analogous work is to be done, the parts carrying the reciprocatory tools can be removed if desired.

The carrier post 12 and the plunger 7 reciprocate, with the parts thereto attached, when a tool is engaged with the arm 16 or with the carrier arm 23, or with both of said arms. v

The operation of the machine will now be understood.

It will be apparent that the eccentric A. is eccentrically engaged with the connecting rod, while it is itseljf also eccentrically en gaged with the hub.
